Middle Fork River Forest Preserve

Middle Fork River Forest Preserve is a 688-hectare preserve in Champaign County, Illinois, roughly 30 miles northeast of Champaign and about 40 minutes from Urbana-Champaign, and was designated Illinois' first International Dark Sky Park by the International Dark-Sky Association in 2018.

Why Middle Fork River Forest Preserve is a top stargazing spot

Getting certified took real investment: between 2016 and 2017 the preserve upgraded its outdoor lighting with more than $20,000 spent on dark-sky-compliant fixtures. That effort earned it the distinction of being the first International Dark Sky Park in the state, and the sky above it now rates Bortle Class 2, the second-darkest classification on the scale used to measure light pollution, giving Illinois stargazers a certified dark-sky destination close to home rather than requiring a trip to a remote wilderness.

What you can see

In 2025 the preserve debuted a dedicated Dark Sky Trail, about a mile long with paved and graveled sections, leading to four designated stargazing areas along the way. Under dark, moonless skies away from the trail's few lights, visitors have a real chance to see the Milky Way, something rarely possible from most of central Illinois, along with far more stars, clusters and planets than a typical backyard reveals.

Visiting Middle Fork River Forest Preserve at night

The Dark Sky Trail includes benches and hammock stands, making it comfortable to settle in for an extended night of viewing. The preserve's North Waterfowl Management Area entrance, at 2554 County Road 3500 North, is open 24 hours, and the Harry L. Swartz Campground offers overnight stays with dark-sky-friendly lighting for anyone who wants to stay through the night rather than drive home in the dark. Day-use facilities include a swimming beach, playground, restrooms, open-air shelters, picnic tables and grills, and dogs are welcome on a leash. For the best results, the preserve recommends visiting during a new moon and during astronomical twilight, using red-light flashlights instead of white ones, and minimizing vehicle and campsite lighting so your eyes and everyone else's stay adapted to the dark.

Best time to go

Central Illinois sits well north of the equator, so the bright core of the Milky Way is best placed low in the southern sky on summer evenings, roughly June through August, while winter nights favour the bright stars of Orion, Taurus and the rest of the winter sky overhead. The Perseid meteor shower peaks in mid-August and the Geminids in mid-December, both good reasons to plan an overnight stay at Swartz Campground. Whatever the season, aim for a night within a few days of the new Moon, arrive early enough to give your eyes 20 to 30 minutes to adapt to the dark, and use only red light once you are out on the trail.

Getting there

The preserve sits in Champaign County, about 30 miles northeast of Champaign and roughly 40 minutes' drive from Urbana-Champaign. See the Champaign County Forest Preserve District's page for current trail access and hours before you set out.

See your named star from here

A certified dark sky like this one reveals far more stars than a typical Midwestern backyard, which makes the Dark Sky Trail's stargazing areas a great spot to track down a named star with a stargazing app and its coordinates.
